Abstract

Traffic congestion caused by traffic volume close to road capacity, where the service level canbe seen from the degree of saturation, ie DS = V / C. Ideally the value of V / C ≤ 0.75. From visualobservations the author, in Palu has frequent traffic congestion especially at peak hours on aparticular road segment. One reason is the high vehicle growth is not matched by growth inroad infrastructure. The purpose of this paper is to evaluate the performance of the streetbetween two signalized intersections in the city of Palu to determine the causes and findsolutions solving traffic congestion.The survey will be conducted to obtain primary data and secondary data analysis required inthe performance of such road traffic data, data geometric road side barriers, interviews withpassengers and motorists. The study was conducted for 4 days at 06:00 to 22:00 with theassumption that the traffic data coverage is 93%.This paper recommends a treatment that is optimized bersinyal roads by managing theintersections along the road segment between intersections with traffic cut off by installing asignal light and each intersection there is an alternative to motorists to avoid congestion, afterallowing back off to prevent the flow of traffic queues length.

Abstract

Asphalt Concrete Wearing Course (AC-WC) is the layer indirect contact with the wheels of the vehicle that makes this layer is easy damage. The use of additive in Asphalt Concrete Mixtures as AC-WC has often done to improve the durability. One of additional material that has been used is hydrate lime. The aim of this research was to know the effect of using lime as additive on AC-WC characteristics.Variations lime used in this study was 0%, 5%, 10%, 15%, 20%, 25% respectively. Characteristic of AC-WC mixture include stability, flexibility, durability, VIM, VMA, VFB and flow of the mixtures. Test characteristic of the mixtures using Marshall Method.Analysis of the relationships the characteristic of AC-WC mixtures with variations of lime using statistical methods is experiment factorial at 95% confidence level or α= 5%. The result of this study was to found that using lime as additives to effect the characteristic of AC-WC mixtures. Optimum Asphalt Content tends to increase due to increased lime content in the AC-WC. The result also found that the best lime content is 15%, Optimum asphalt content is 6.67% with an increase stability value of 9.75%, durability value of 1.39% and flexibility value of 11.61% when compared to the characteristics of AC-WC mixture without additives lime.Keyword:  Lime, Asphalt Concrete Wearing Course (AC-WC)

Abstract

The aim of this research is to evaluation of performance intercities public transportation on route of Palu – Poso Central Sulawesi base on travel time, operation speed, number of passenger, load factor, vehicle operation cost and transport income. The result of this research show that  operation of intercities transport still eligible base on the speed of operation and amount of vehicle operation cost on the income of the operator of intercities transport, althought benefit of the operator is very law.
